Re: HOW TO: Set up the HP TX2z and Dell XT & XT2 (N-trig digitizer) in Ubuntu

Hi, I'm really new to linux so I decided to try ubuntu 12.10 on my old HP touchsmart tx2 laptop.
One big problem is the wireless switch (light) is off doesn't turn when I turn it.
I did some research and found some solution but I live in a dorm so I can't go plug my laptop to a router with ethernet cable.
Is there anything I can do to fix this? I really like it but I don't have an internet access .
Thank you

Forgot to mention that the chip is Broadcom BCM4312
Is there a way to fix this without wired internet?

Re: HOW TO: Set up the HP TX2z and Dell XT & XT2 (N-trig digitizer) in Ubuntu

Hi all.

Could some one with some knowledge of these things tell if I'm seeing normal behavior with my n-trig duoSense touchscreen.

When I start up evtest and touch the screen, I get a constant stream of data displayed while I touch the screen without moving my finger. On lifting my finger off the screen, evtest reports ABS_MT_TOUCH_MAJOR, ABS_MT_TOUCH_MINOR, BTN_TOOL_DOUBLETAP and then BTN_TOUCH.

When I drag a finger across the screen I see exactly the same result. It would appear to me that the driver does not work correctly. Should I see a constant stream of data even when I don't move my finger? Or should it register a BTN_TOUCH value 1 and then BTN_TOUCH value 0 as my mouse does and only show a constant stream of data when I move my finger across the screen.

I'm using the standard kernel module that comes with standard kernel version 3.6.0. I tried compiling the latest module listed on here for my kernel version, but it wouldn't load. I have no idea what firmware version my screen is, as the firmware tool doesn't work for me giving no return result. And I don't own or have a version of windows anywhere near my house.

All I can tell you is that my vendorID is 1b96 and the prodID = 0007.

The screen is a 10" LG LVDS LCD with an usb n-trig touch screen combined. xinput sees a touchscreen, pen and multitouch.

The touchscreen seems to work ok, but many apps are just confused by the data it keeps sending out registering everything as a drag event. It just doesn't seem right to me?

The constant stream of events is normal. That version of the driver is using the older MT protocol. In that protocol, a pause in the stream indicates termination of contact (instead of a specific button release event).

The BTN_TOUCH, ABS_X, ABS_Y, etc events are standard absolute pointer events, which only send updates when a particular item changes value. Hence, just the single BTN_TOUCH events at the start and end of the stream.

As long as the events stop when you're not touching the screen, that's normal.

I for some reason you want a version which uses the newer protocol, that can be arranged. But realistically it's sensitive enough that you probably still see a near constant stream reporting minute changes.

I have Ubuntu 12.10 installed on an HP Tx2z and I'm interested in getting touchscreen and rotation installed on this machine. Just a few days ago I got AMD Catalyst installed which made a big improvement, my stylus now works in apps such as Pinta & Mypaint. However from reading this thread it looks like the touchscreen will hard to install on 12.10 and I will have to downgrade. I really don't want to do that at this point as my setup is actually quite stable now, any chance at all that I would be able to get touchscreen on 12.10 in the reasonably near future? If not then (sigh) I guess I could reinstall with 12.04 or whatever is best. I an open to suggestions.
